[0001] The utility model relates to the technical field of automotive parts, and particularly relates to an anti-fracture automotive spring backing plate. Background Technique
[0002] Automotive spring backing plates refer to the gaskets installed on the springs of automotive shock absorbers. Their functions are to improve driving comfort, extend the service life of shock absorbers and springs, reduce driving noise, improve handling performance. The spring backing plates can prevent the shock absorber from contacting the vehicle body, thereby protecting the shock absorber and improving the shock absorption effect, making the vehicle more stable during driving and improving driving comfort.
[0003] Since the spring backing plates bear periodic loads and impacts in the vehicle, these loads may cause the backing plates to undergo fatigue fracture, which will affect the service life of the spring backing plates and the safe driving of the vehicle. For this reason, an anti-fracture automotive spring backing plate is proposed. Content of the Utility Model
[0004] The purpose of the utility model is to provide an anti-fracture automotive spring backing plate to solve the problems raised in the above background technique.

A connecting plate is provided on the lower surface of the spring backing plate body. Two connecting blocks are fixedly connected to the upper surface of the connecting plate. A first installation groove is opened on the upper surface of the connecting block. A transmission rod is rotatably connected to the inner side wall of the first installation groove through a bearing. A buffer groove is opened on the lower surface of the spring backing plate body. Two return plates are fixedly connected to the upper surface of the inner side wall of the buffer groove. A sliding rod is fixedly connected to the inner side wall of the return plate. A slider is slidably connected to the outer side wall of the sliding rod. The outer side wall of the slider is slidably connected to the inner side wall of the return plate. A second installation groove is opened on the lower surface of the slider. The inner side wall of the second installation groove is rotatably connected to the transmission rod through a bearing. A first spring is fixedly connected between the slider and the return plate. The first spring is sleeved on the outer side wall of the sliding rod. A damper is fixedly installed between the upper surface of the inner side wall of the buffer groove and the upper surface of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:
[0012] In the present utility model, the force received at the bottom of the connecting plate is transmitted to the connecting block, and then transmitted to the transmission rod through the connecting block. While the transmission rod rotates, the force is transmitted to the slider. The slider slides on the outer side wall of the sliding rod and compresses the first spring. The first spring can absorb the impact energy and cooperate with the damper, thereby reducing the influence caused by the impact, preventing the backing plate from suffering fatigue fracture, not affecting the service life of the spring backing plate, and ensuring the safe driving of the vehicle.

A buffer groove 7 is opened on the lower surface of the spring backing plate body 1. Two return plates 8 are fixedly connected to the upper surface of the inner side wall of the buffer groove 7. A sliding rod 9 is fixedly connected to the inner side wall of the return plate 8. A slider 10 is slidably connected to the outer side wall of the sliding rod 9. The outer side wall of the slider 10 is slidably connected to the inner side wall of the return plate 8. A second installation groove 11 is opened on the lower surface of the slider 10. The inner side wall of the second installation groove 11 is rotatably connected to the transmission rod 5 through a bearing. A first spring 12 is fixedly connected between the slider 10 and the return plate 8. The first spring 12 is sleeved on the outer side wall of the sliding rod 9. A damper 13 is fixedly installed between the upper surface of the inner side wall of the buffer groove 7 and the upper surface of the connecting plate 2; when a load and impact are applied to the bottom of the connecting plate 2, the acting force is transmitted to the connecting block 3 and then transmitted to the transmission rod 5 through the connecting block 3. While the transmission rod 5 rotates, the acting force is transmitted to the slider 10. The slider 10 slides on the outer side wall of the sliding rod 9 and compresses the first spring 12. The first spring 12 can absorb the impact energy and cooperate with the damper 13 to reduce the influence caused by the impact.
[0022] In this embodiment, specifically: a second spring 14 is fixedly connected between the upper surface of the inner side wall of the buffer groove 7 and the upper surface of the connecting plate 2; to further buffer the impact of the acting force.
